Jacksonville Jaguars rookie CB Aaron Colvin had some work in the base defensive packages in Week 15, and he played some in place of CB Dwayne Gratz instead of playing nickelback. The team could view Colvin and CB Demetrius McCray as starters heading into next season, with Gratz taking over the nickelback role.

The Jacksonville Jaguars are extremely thin at cornerback heading into the team's Week 8 game, with CBs Alan Ball (biceps) out, and Dwayne Gratz (hip flexor) questionable. There is still a chance Gratz could play, and will test the injury Sunday morning. "That's the plan as of right now," Gratz said. "See how it goes tomorrow and then on game day we'll work it out and then go from there."
